1 Introduction Congratulations on your purchase of a ZyXEL Omni TA128. The TA128 sets new price/performance standards for the explosively growing Internet and telecommuting applications market. When used with off-the-shelf Internet or remote access client software, the TA128 enables mobile or home users to connect to the Internet or branch offices over ISDN lines Hassle Free! The same device also allows a user to connect to the analog world via a modem, fax machine, or telephone connected directly to the TA128. To take advantage of constant new developments, the TA128 employs flash EPROM, which allow for convenient uploading of newly available firmware, preserving your hardware investment. The TA128 supports both D and B Channels protocols. For the D Channel, it supports DSS1, 1TR6, DMS-100, AT&T Custom, and NI-1. For the B Channels, X.75 SLIP, V.120, V.110, PPP Async-tosync Conversion and Bundle (128Kbps). ZyXEL's expertise in data compression has been brought to the TA128. With its V.42bis compression on the B Channels using either X.75, V.120, or STAC/LZS compression over PPP/MP the TA128 can effectively communicate at speeds up to 460Kbps over ISDN lines. The TA128 also has two analog ports for handling fax machines, modems, and telephones. Two different analog devices can communicate over the two B channels to two different locations simultaneously, so you can send a fax and make a voice call at the same time. The analog ports also recognize standard DTMF tones as well as pulse dialing. 1
